Y'rRAv'n'Linie Loon FOR een cARRrAGns.

For gun'ca'rriagcs having,- a large range. and' provided with aquadrilateral' support on the ground composed of two-wheels and twospades, one of the means employed in ordei` that 'the' said'quadrilateral support may be adapted to the ground consists inpivoting'ithe' vehicle axle to the carriage by means a longitudinalspindle.` Suitable locking lmeans must be provided for lthevpivot inconditionsof travel. Y

When the sai carriage is provided'with an elastic suspension device forroad travel, consisting 'for example of plate Ispring-sor like elasticmeans interposed between Athe can' riage'and'the,axle, it isnecessaryjto vprovide locking means' in order vthat the `suspensionparts shall not be subjected to the Itiring shocks'. E

Thepresentinventionhas for itsobject to provide'fan ai'rangementAwhereby Ethe locking may be obtainedfineither ofl the abovementionedcases by theo'pcration of a single common control device in eitherdirection, exclusive of all other operations, and chiefly without beingobliged to raise the said carriage in order to provide for the expansionol' the elastic parts of the suspension.

The said arrangement comprises locking elements and a control foractuating the said. elements. When the control is operated in a givendirection, it brings the locking` elements into the firing position; thelateral inclination is le't free while the vertical motion is preventedby the said locking means. By operating the control in the contrarydirection, the locking devices are brought into the position for roadtravel; the lateral inclination is now prevented, while the verticalmotion is released.

rlhe appended drawings show by way of example which is no wiselimitative, two emhodin'ients of the said invention.

Fig. l is a front elevational view of the first form ot construction,the carriage being,r reduced to its cross-piece.

Figs. Z and 3 are cross-sections on the lines iii- A and B-B of Fig). lrespectively.

l and 7, relate to the second form of the device, with the springremoved.

Fig. l0 is a section on' the line D.-D o 'l Fig. y

ln the first form or" constructiointhe locking device consists of twowedges l which are slidablc on the axle 2 by means of a control screw 8having` two threads in con trarydirections, each thread being engagedwith corresponding threads formed in the said plates; the said screw isrotated for instance by a lratchet lever or a-handlc il. At the middlepart of the axle 2 are two extensions 5 serving` supports and guides'for the said wedges.

The wedges may be moved apart or may be brought together until. they arein Contact; when in contact, their upper surfaces coineide so as to forma cylindrical surface oi. revolution 6 whose centre line is the loi@"tudinal pivoting axis. The crosspiece 7 the carriage has acorresponding' cylindrical sur tace 8 whereby the carriage is caused tobear upon the aXle for the firing operation, and one ol' these elementscan be laterally inclined with reference to the other. Upon the saidcross-piece is revcluble an axle 9 which constitutes the longitudinalpivotand to which are secured at the middle part two transverse platesprings l0 and ll v-.fhose ends are attached to the vehicle asile byshackles; on the axle 9 is also revoluble retaining strap @Xtending,`below trie said 'wedges when in the tiring' position and preventing thecross-piece 7 dtrom being raised from the vehicle axle. The. saidcross-piece is provided with two pairs et downwardly eftcnding lugs 13having thereon the roller.V le with which the said wedges may co-operatewhen moved apart.

In this posi-tion oli the wedges, the sin face 8 of the cross-piece isallowed to descend, passingbetween the said plates which prevent anymoven'ient of inclination et the carriage relative to the axle.

The control rod for the said wedges i.: through the centre oil thevehicle axle and is connected to the saine in an elastic manner by meansof the springs l5, whereby all iai ring motion between the rollers andwedges is obviated when in the position of travelf In the second form ofconstruction, Fien.

and l1, which are attached to the aide by shackles, are fitted at themiddle part inte 8, 9 and 10, the plate suspension snrings l0 ses themembers 'l (3 which comprise aniextension 17 andare traversed `by a.longitudinal axle 9. To the latter are pivoted on the one hand thecrossfpjece'4 of the carriage and on the other hand tivo pairsI of'loentarrn's 18 Whose ends 19 can "lieinaintainedeither in the adjacent orseparated positionffor. instance by means of a rod with doublescrew-thread 90 which isiturned V1oy1a handle or a ratchet lever 4 andthe rod and link gear 21 which is properly jointed and sliclahle.

Vhen in the separated position, the two pairs-ot arms are held in tivoout-out portions 22 of the vehicle axle, thereby locking theisuspensionby connecting the vehicle axle with thepivotinzg` axle 9. In this eventthe carriage can loe inclinedy laterally With reteneneertothe vehicle.axle by pivoting on the axle 9.

Wlieni moved together, the two pairs of' armsy comeinto` contact withthe extensions 17 ot' the members 1G whilst their ends QB hold-theoross-piece 7, so that theisaid arms and thecross-piece heee-ine securedto the members 16 into which the vehicle springs arewlitted; i

The' carriage is thus suspended from the axle in an elastic inanneri andcan nolonger pivot upon the axle 9.

lClaims:

1. In afield gunvvith Wide range, the coinbination of a carriage, anaxle, an elastic slaaiension lwiwren the said aigle and the said'carriage, a longitudinall pivot about which the said carriage can turnrelatively to the said axle, and a connnon. mechanism `for locking the`said elastiojsuspension and 'for locking thi,` carriage'upon its'pivot, said mechanism being` adapted to allow of locking,r Athe elastiesuspension at same time as the unlocking of the carriage-.upon thelongitudinal pivot, or the unlocking of the suspension a; same time asthe locking of.` the' carriage upon this pivot.

2. In a field .f 'annon having a great tiring range, the, combination ofan axle,.trans.erse plate springs pivoted at' the ends to the said axle,a longitudinal sha'lft mounted at the middle of the said springs, a guncarriage pivoted upon the said. shaft, movable elements which act intheir irst position to permit the rotation oit the carriage on the saidlongitudinal shalt Whilc'preventing all vertical motion thereofrelatively tothe said axle, and in the second position tofprevent allrotation oit the gun carriage onI the said shaft While pern'iitting theascent ol thc carriage relatively to the said: aXle,vand` a -control`rod with right andV left hand screwthread which is screwed upon thesaid ele-A inentsand serves to change their position.
